UNIVERSAL JOINT GASING.

APPLICATION FILED mlm, 190s.

and the `intermediate, bellows Section expands on one'side and contracts on the other veiy freely so as to permit this motion.

lhis casing' comprisingthe two sections E and F and Lne intermediate-bellows sections is practically oil tight, and a suii'cient quantity of a lubricant suitable for lubrieating the universal joint may be put into lthis casing through any sort of filling hole,

as, for example, that in which thepipe e is secured.

The form of the invention shown in Figs. t and 5 includes a ring K and two bellows sections, H and H, one connected with said ring and one with the casing section E, and the other connected with said ringand with the casing section F. This ring is hinged on a diametrical axis to 'ears e2 on the section E, and is also hinged on a diametrical axis, at right angles `to tlie'tirstmentioned, to ears fr on the section F. 'lshis is a rather morel `expensive form of the device, but 1t has the advantage of preventing the bodily udwise movement of the metallic sections`relative to each other,aii'd it also'has the advantag, of permitting the complete universal movement in all directions of the casing' sections E and F. y

Havingr described my invention, I claim:

Al. A casing for universally coupled shafts comprising in combination a fixed casing section surrounding' the end of one shaft,

the said shaft being` independently rotatable section which surrounds one shaft, the said shaft being independently rotatable' in Asaid casing, the said section being provided with an oil-tight joint surrounding the said shaft,

a second casing which embraces the other shaft in which the said other shaft is independently rotatable, said second casing being provided with an oil-tight joint in which its shaft rotates, means for flexibly connect-l ing the said casing sections whereby they may move with respect to each other', but the second section is held from rotation, and a fiexible intermediateD easing which is secured at its ends to the first mentioned casings. Y

3. 'iX-casing for universally' coupled shaft-sf: comprising" in combination a fixed casing section which surrounds one shaft, saidl shaft being independently rotatable therein, a second casing section which embraces the other shaft and in which the latter shaft is' independently rotatable, means for iexibly v connecting the said casing sections permitting; movement between the same but preventingl the second casing section from rotation, and an annular accordion bellows section which is connected'at its ends with the two casing' sections first mentioned.

4. A casing' for universally coupled shafts eon'iprisinur a metallic section which surrounds one shaft and is fixed to the bearing` thereof, a second metallic section which embraces the other shaft and in which said shaft ifi freely rotatable, a packing' being interposed between said shaft and section, the said two metallic sections' having diametrically disposed ears which are pivoted together, and a iiexible intermediate section which is respectively seeuredto the two nietallicsections. u

In testimony whereof, I hereunto affix my. signature in the presence of two witnesses.

CHARLES SCHMIDT.
